PAPER-SORTING TABLE.

Application filed September 5, 1922. Serial No. 586,383.

To all whom it may concern:

Be it known that I, JOHN H. REEDY, a

citizen of the United States, and a resident.

of Hamilton, in the county of Butler and State of Ohio, have invented acertain new and useful Paper-Sorting Table,of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification. y

My invention relates to devices for sorting paper upon which paper isdeposited by trucks or otherwise and from which the sheets are inspectedand counted and distributed inthe desired manner, The great diliicultyin the sorting of large bundles of paper in the past has been that thebundles are high, bulky Vand very heavy, and that either at the startthe bundle is too high, or at the close it is too low for convenientreach by the operator, `Also it has always been a dilicult propositionto properly deposit a bundle of paper sheets to be sortedor counted on atable from the factory trucks on which the bundles are transported,since it requires jacking up prior to deposit and a lateral deposit fromthe truck, even after jacking up. d Also in machines where the paper isbrought directly from a cutter onto a counting and sorting table, it isa great disadvantage to have a fixed surface or table onto v which thesheets are shiftedone by one,

since if the support ishigh enough at thestart of cutting a batch ofsheets, the pile is too high for convenient manipulation toward the endof the operation.

It is thus the object of my invention to provide a sorting table forpaper sheets and the like, which can be moved by power to any desiredheight, such as five feet, and as low as flush with the floor ofthelfactory, and can be shifted gradually from any position to anotherwithin this range, so that the top of the bundle of sheets at any onetime will be conveniently placed, and so that a truck can be rolled ontothe support and unload its bundle downwardlyLV into place.

I also have as an object the provision of a hydraulic operation for thesupport, so that it can be readily moved by power and will keep itsadjusted position against the] heavy "loads which it isv required towithstand.

by that cert-ain construction and arrange- I accomplish my objectslabove set vforthment of parts to be hereinafter more specilicallypointed out and claimed.

In the drawings, Figure 1 is a central vertical section of the device.

Figure 2 is a top plan view thereof.

Figure 3 is a detail section through the piston.

Figure 4 is a bottom plan view of the piston. v

I have shown a well or casing 1 of suitable structure, such as concrete,and a floor 2 erected on the concrete base. The cylinder 3 of heavyconstruction has a flanged head 4.- which rests on the base of theplatform countersink 5 `in the concrete. Thel head Dis preferably helddown -by suitable bolts (not shown),

There is a water pipe 6 running to the drain and a service water pipe 7containing water under pressure. Each pipe has a valve 8 and 9,respectively. i. y r y The support or table 410 is formed of a heavilyconstructed metal plate with a cen'- tral boss 11 beneath it, in whichengages the large head 12 of the piston, rod 13, the piston rod beingguided in the head of the cylinder.

The piston is formed of a central member 14 of cylindrical shape havingon its upper and lower faces, heavy metal plates 15, 16,

19 thereon, and a heavy coiled spring 20 set u around the rod bears onthis collar and on the periphery of the boss 21. This spring serves as abuffer to take up jars and holds the piston normally', somewhat abovethe base'of the socket in the boss 21.

' I have shown the boss beneath the table as partially oif-center, thereason for this being that sheets of different sizes are often countedor sorted on tables of this character, and the of-center'placing is soarranged that large sheets and small sheets in bundles may be placed onthe ltable with the center ofl gravity maintained alon the axis of thetable boss at all times. hus the size and position of the largest sizedsheets likely to be used on any one installation will govern theposition of the boss olf-center, and the operator will be directed toplace his larger size sheets in a more or less definite posi'tion on thetable.

In use *the Water supply valve is turned on to permit water to flowthrough the pipe 22 from the common connection or T 23 of the waste andsupply pipes into the base of the cylinder. This water forces the pistonupwardly until the valve is turned oif or the piston is as high as itwill go. When it is desired to lower the table, the supply valve isturned of and the waste valve opened, whereupon by gravity the tablewill force out the sustaining column of water and the table settle downunder con- .trol of the waste valve until it has reached -a point withinthe counter-sink and on a level with the floor.

Thus in ltaking oif from a cutter the table will be fed up to y,thedesired height and gradually lowered as the bundles pile up to maintainthe desired' level. In loading onto a truck, the easiest height can bear rived at. In loading the table from a truck, it is moved to the levelof the floor, the truck run over it and dumped.

-In working on a pile on the table, the height of the top of the bundleis maintained where most desirable and the column of water beneath thepiston is a non-compressible medium capable of sustaining any load thatthe mechanical parts will sustain, so long as both valves are closed.

Tables of this character are often used in rows and any revolution ofthe table would not be desirable. With this in view it is preferred tohave the piston rod keyed by means of a key-way 24 in the rod engaging akey or projection in the cylinder head. A like key is provided for thesocket in the tableq boss and the upper end of the piston rod is fittedinto the boss, so tha-t its keyway registers with the key.

The advantage of working on a table of 'this character with heavybundles of paper what I claim as new and desire to secure by LettersPatent, is

1. In combination with a buildingiioor having a recess therein to housea table top, a table top, land means located beneath the floor to carrysaid table top, said means being controllable from a point outside ofthe table to move the table top to a variety of horizontal positionsabove the floor, for the purpose described.

2. In combination with a building oor having a recess therein to house atable Ltop to be flush with the loor, a table top, and a hydraulicpiston and piston rod, said rod being engaged with the table top to moveit to desired positions above the recess, said hydraulic piston and rodbeing located beneath the said building oor.

3. In a sorting tablefor paper bundles, the combination with ahorizontal support for paper bundles, able carrier for said support,adapted to locaite and hold the support at a variety of positions, saidcarrier comprising -a hydraulic piston and piston rod, the piston rodbeing in engagement operative control of the piston located out.
